A Swedish company currently develops and develops a new type of green packaging material called TPR. This packaging material is suitable for various processing operations such as hot-press molding, blow molding, injection molding, and extrusion molding.
According to reports, this TPR packaging material is made of calcium carbonate bonded to polyolefins by a special process. Its structure is very similar to that of egg shells. It contains 95% of calcium carbonate and the remainder is polypropylene as a binder. Since the calcium carbonate resources are extremely abundant, the source material for producing this TPR green packaging material has a wide range of sources, and its waste has no pollution to the environment.
